Application June 25, 1934, Serial No. 732,377 *Y 3 Claims. (Cl. 28-20) This invention relates to a deviceV for cleaning the central passages in quills and is an improvement of the device described and claimed in my Patent No. 1,945,654, granted Feb. 6, 1934.

Machines have been employed for removing the weft-residue windings upon the exterior of thequill or bobbin by means of Scrapers or knives. Means are employed for feeding the quills or bobbins to the stripping apparatus and means are also employed for removing the quills or bobbins after they have been cleaned. These machines are automatic in operation but they only partially clean the quills due to the fact that the interior of the quills carry some lint which must be removed toprevent this lint aiecting the proper positioning of the bobbin on its spindle. In some mills the quills or bobbins are 4cleaned manually by means of tools or wires which are inserted through the central bore but where the central bore contains a great deal of lint these tools have a, tendency to pack the openingv so that the quills or bobbins must be discardedas useless.

An object of the present invention is the provision of a device for cleaning the axial passages of the quills or bobbins by forcing compressed air through the passages when the quills are placed in operative position for the removal of the lint upon the exterior of the quills.

Another object of the invention is the provision of a, compact and simple device which may be readily attached to a machine which is adapted to clean the weft residue from the exterior of quills or bobbins, the device being so constructed that the lint from the interior may be removed simultaneously by a sudden blast of compressed air through the central passage in the quill.

A further object of the invention is the provision of a device for forcing compressed air through the axial passages of quills or bobbins for removing lint collected therein in which a nozzle is provided having a slot for a portion of its length so that the quills may be readily dropped into the slot and be positioned in alignment with the air passage in the nozzle with means for automatically pressing the nozzle into sealed engagement with the end of the quill, the device including means for automatically releasing a blast cf compressed air through the nozzle and the quill at approximately a time when the nozzle has been pressed into operative relation with an end ofthe quill.

A; still further objectv ofA the invention is the j provisionA of. a device.Y for: removing lint from the lint and clog the central interior. oi quills-or bobbins in-Whicha nozzle is moved into. operative engagement with an` end` of a quill at atime when the quills are automatically receivedV by the nozzle, said means including an air valve which is operated by a block 5 supported by a pluralityl of pivotal connections with a fixed support so that when the nozzle is shifted the block which is pivotally connected to the nozzle structure will be moved into. operative engagement with the stem of an air. valve for re- 10 leasing air at the limit of movement of the reciprocating air nozzle.

This invention will be best understood from a consideration of the following detailed, description, in View of the accompanying drawings form- 15 ing a part of the specification; nevertheless, it is. to be understood that the invention is not conined to the disclosure, being susceptible of such changes and modifications as deiine nomaterial departure from the salient features. of the inven- 20 tion as expressed in the appended claims.

with respect to the engagement of the nozzle 22 with the reduced end of the quill 26.

It will be appreciated that after the lint has been blown through the central passage of the quill 26 it will pass out through the passage |06 and be projected downwardly after which the nozzle 22 is returned to its inoperative position by the spring 25 and the quill 26 is removed to permit the application of other quills.

The device shown in Figs. 8 and 9 is one which is adapted to be attached to the push head of the Terrell quill stripper disclosed in one form in Patent 1,749,128, dated Dec. 1'1, 1929.

In this instance a table |50 is provided having a longitudinal slot |51 and a depending iiange |52. This table forms a part of the quill stripper.

A traveling push head |53 is mounted on the table |56 and is moved back and forth by means of ears |513 connected with a crank arm |54a which is connected with the stripper and .reciprocated back and forth for causing the push head to be operated. This mechanism forms no part of the present invention and therefore no further description appears necessary.

Mounted on the push head |53 is a push head block E55 which is adjustable longitudinally of the push head |55 and this adjustment is provided by means of a slot |56 formed longitudinally of the slide and through which projects a pipe |51 having a threaded portion |58 upon which is threaded a nut |59 for holding a corrugated washer |66 in engagement with a knurled or ribbed surface ii. 'Ihe upper end of the pipe is also threaded into an opening |62 formed in the bottom portion of the push head block |55.

When it is desired to adjust the block longitudinally of the slide |53 to provide for quills of various sizes, the nut |59 is loosened and the block and the pipe |51 are moved along the slide with the pipe riding in the slot |56. When the proper position of the block has been procured the nut is again screwed into position.

The block is provided with a socket or bobbin tip seat |63 adapted to receive the small end of the quill with the longitudinal passage in the quill being adapted to be aligned with a passage |64 which communicates with the passage |62 and the pipe |51.

The pipe |51 is placed in communication with valve casing |65 by means of a pipe |66 and an elbow |61. This valve casing contains a valve which is operated by a stern |68 projecting beyond the vaive casing.

A lever is pivotally mounted at 1| at its upper end on a bracket |12 which is secured to the valve casing |65. This lever is provided with a toe |13 which is adapted to engage the projecting end of the valve stem |68. The lower end of the lever is bifurcated at |14 and spans one end of a link |15. The bifurcated portion of the lever is pivoted at |16 to the end of the link.

The link is provided with an abutment |11 and is retained in position on the outer end of the link by means of a bolt |18 which may be placed in any one of a plurality-of perforations |19 formed in the end of the link to provide for the change in position of the abutment |11. This adjustment of the abutment is necessary where quills of diierent lengths are employed as will be presently seen.

The link |15 at its outer end projects through a passage |80 formed in the bottom of a bar |8| 3 which is secured at |82 to the ange |52. The inner end of the abutment |11 engages an enlargement I 83 formed on the outer face of the bar |8|.

The operation of my device is as follows: The quills are fed to the stripper automatically in a well known manner and as the push head |53 is reciprocated to the right in Fig. 9, the abutment |11 moves away from the boss |83 or the bar |8| with the link |15 moving through the slot |80. At this time the lever |10 is rocked with the lower end of the lever being moved to the left so that the toe |13 will be moved away from the stem |68 of the valve. At this time as is well known the quill will be removed from the push head block |55 and as the push head |53 is moved towards the left another quill drops in position with the small end of the quill being received by the socket |63 and the open end of the quill will bein alignment with the passage |64. Continued movement of the push head to the left will carry the pipes |51 and |66 and the ilexible hose |90 which is connected to a source of air under pressure also to the left and the link |15 will also be drawn to the left carrying the abutment |11 towards the boss |83. At this time, however, there will be no pressure exerted on the lever |10 so that the valve in the casing |65 will not be operated by the stem |68. However, after the head |53 has been moved within a fraction of an inch of its limit of movement, the abutment |11 is so po-sitioned on the link |15 that it will come in contact with the boss |83 and hold the link |15 against further movement. This will cause the lever |10 to be rocked and the toe |13 will operate the valve stem |68 and open the valve in the casing |65 and cause a blast of air to be discharged from the passage |64 through the quill, thereby blowing out the waste from the interior of the quill and thus prevent such lint from being carried in the manufactured cloth.

The blast, however, is only momentary since the push head is returned immediately to the right to permit closing of the valve. The speed of operation is rapid so that no prolonged blowing is had nor is it required.

What I claim:

l. In combination with a bobbin stripper of the type employing a sliding cross-head carrying a pair of gripping jaws for gripping the head of the bobbin to draw it through the usual scraping knives, a slidable tube carrying a nozzle at the end adapted to engage the tip of the bobbin while the same is grasped by said jaws, the tube being connected at its other end to a source of lcompressed air, a valve in said tube, and means actuated by the forward movement of said crosshead to not only advance said tube to put its nozzle into contact with thetip end of the bobbin but also to open said valve.

2. The structure cited in claim 1, said means embodying a slidable rod actuated by said crosshead, a lever associated with the tube and actuated by said rod.

3. The structure recited in claim 1, said means embodying a spring positioned and arranged to be tensioned by said forward movement of the cross-head and released by the return movement of the cross-head to restore all the parts to normal position.
